2004/9/8Stressing is a rail engineering process. It is used to prevent heat and cold tension after installation of continuous welded rail (CWR). Environmental heat causes CWR to expand and therefore can cause the fixed track to buckle. Environmental cold can lead to the contraction of the fixed rail causing brittleness and cracks. Before it is

Chemical formula: SF₆Melting point: −64 &C; −83 &F; 209 KMolar mass: 146.06 g/molSolubility in water: 0.003% (25 &C)OverviewSulfur hexafluoride (SF6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non flammable, and non toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L). It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earth's troposphere reached 10 parts per trillion (ppt) in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF 6 gas contained in its medium and high voltage switchgear. Uses in magnesium, aluminum, and electronics manufacturing also hastened atmospheric growth.

Current interruption in a high voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF6), having excellent dielectric and arc quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity.

Maglev (from magnetic levitation) is a system of train transportation that uses two sets of magnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction. Along certain "medium range" routes (usually 320 to 640 km [200 to 400 mi]), maglev can compete
